Workaround: Do not access non-VOB related mounts when cd?ing into a view-extended path. On Linux, the view-extended path will not cover objects that do not reside within MVFS and thus would require a setview shell to accommodate those types of file level access. This restriction is due to a kernel level limitations on third party filesystems.
